Title: A remote observation system
IPC: H04Q9/16
Filed: 1965-06-10
Abstract: 1,105,973. Electric selective signalling. TATEISI ELECTRONICS CO. 10 June, 1965 [13 June, 1964], No. 24650/65. Heading G4H. A central station joined by a single pair of lines to a plurality of field stations sends a sequence of call pulses each followed by a predetermined number of scan pulses on one line, and a counter at each of the field stations operates an " and " gate after a predetermined count of call pulses to permit the scan pulses to scan the points at that station by means of a second counter connected to a diode matrix connected to the switch points, wherein the matrix produces a result pulse when any one of the switches is closed indicating a disorder, which pulse is transmitted on the second line to the central station where it is indicated. Counters at the central station count the call and scan pulses such that a diode matrix can determine from which field point the result pulse is generated and activate the appropriate " annunciator ". The scan pulses are generated at the central station by a pulse generator and are counted, whereby after a predetermined count a pulse of opposite polarity representing the call pulse is also generated.

Title: Improvements relating to electrical switching circuit arrangements
Inventor: SCOLES GRAHAM JOHN
IPC: H03K3/53
Filed: 1954-08-25
Abstract: 801,584. Pulse generating circuits. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Sept. 12, 1955 [Aug. 25. 1954], No. 24744/54. Class 40 (6). A high voltage pulse generating circuit arrangement comprises a capacitive pulseforming network which is connected to a charging source via a switching arrangement whereby the polarity of the network is recurrently reversed and the network has high resistance connections connected to the charging source so that in operation the D.C. voltage level of the network when all the switches are open is clamped. Fig. 1 shows a high voltage pulse generating circuit in which the switches S1-S4 are gas discharge gaps such as rotary spark gaps, thyratrons, ignitrons or trigatrons. Capacitor C1 is charged from a D.C. voltage source so that when all the switches are open the pulse-forming network delay line DL is charged via resistors R1 and R2. When switches S2 and S3 are closed the network DL is connected to the external circuit comprising the load R1 in a reverse sense so that it discharges and a pulse is obtained across R1. When switches S2, S3 are opened, switches S1, S4 are in their turn closed and a further pulse is produced across load resistor R1. The values of resistors R1 and R2 are so chosen that the potentials at point B and D of the bridge do not vary greatly and are held either at the supply voltage or zero as the case may be so that the voltages across the switches do not exceed that of the supply. In a modification, shown in Fig. 2, further resistors R3 and R4 are included so that the points B and D are connected to potential dividing points across the reservoir circuit comprising capacitor C1.

Title: Apparatus for processing light sensitive film
IPC: G03D3/06
Filed: 1966-06-06
Abstract: 1,135,620. Photographic processing apparatus. HOUSTON SCHMIDT Ltd. June 6, 1966 [June 4, 1965], No.25188/66. Heading G2A. Apparatus for processing a strip of lightsensitive material comprises a wet processing section closely adjacent to a drying section through which the strip is fed by rollers outside the sections so as not to contact the section walls. The wet section consists of a succession of treating chambers 21, two of which are shown. A strip is fed into a chamber 21 through a slit 45 in one end-wall, then through slits 44 formed between cross-pieces 35, 40, and then out through a slit 45 in the opposite end-wall. Processing liquid, heated to the required temperature by e.g. thermostatically controlled heaters in a reservoir (23) Fig. 1 (not shown), is pumped into circular channels 46, 48 extending across the width of the chamber. The liquid is forced through slits 47, 49 into the slits 44, where it acts on the film strip, the pressure of the liquid on either side of the strip being the same, thus causing the strip to float in the slit 44. Excess liquid drains back to the reservoir (23) via an opening 28. The slits 45 at the inlet and outlet of the chamber 21 are supplied, via channels 54, 55, with gas, e.g. air, under pressure. This air acts as a "gas seal" for the chamber 21, and prevents processing liquid being carried from one chamber to the next. Excess air escapes through a vent 30 baffles 33, 34 being provided to condense out the processing liquid carried by the escaping air. The reservoirs associated with successive chambers may contain a developer, a fixer, a washing solution and a hypo clear solution. A light-tight casing may be provided over the appropriate parts of the apparatus. The drying device is of a similar construction, heated air being blown on to both sides of the film. In another embodiment Figs. 7-11 (not shown) the "gas seals" are provided at inlet and outlet slits of a chamber containing processing liquid to above the level of the slits, the film strip being passed through the liquid in the chamber.

Filed: 1937-09-17
Abstract: 499,518. Airscrews. BRITISH THOMSON-HOUSTON CO., Ltd., and ROE, E. W. Sept. 17, 1937, No. 25306. [Class 114] In a variable-pitch screw propeller each blade has a hollow root portion rotatably mounted over a spigot on the boss and a threaded sleeve member is located between them, one end of it terminating in a ram, the blades and spigots having relatively inclined threads co-operating with threads on the sleeve member whereby, when pressure is applied to the ram, the parts are displaced so as to rotate the blades for pitch variation. The blade 4 has an inner bush 8, which is secured thereto by screws 10 and carries a bevel wheel 25. This sleeve is splined at 9 to engage splines on a ram sleeve 11, the upper part of which projects into a chamber 22 which is in communication by ducts 21 with passages in the propeller hub and shaft leading to a fixed pipe supply 13. The inner part of the ram member 11 has helical splines which engage corresponding helical keys on the boss spigot 9. With increase in revolutions, the sleeve block 4, under centrifugal force, tends to move outwardly and restraint thereto is applied by the fluid pressure in the space 22. A second set of supply ports 24 may be formed at a different position relative to the travel of the sleeve whereby the degree of movement of the sleeve can be controlled by using different pressures of oil supply. Where the weight of the ram members 11 is not sufficient, the gearwheels 25 may gear with others on axes at right-angles which are secured to similar movable sleeves, but these do not directly operate other propeller blades. Alternatively, there may be fitted at the base of the sleeve a spring supplementing the centrifugal force and tending to cause it to move outwards, in which case the member 11 can be lighter in weight.
